This study investigates the collection and storage of specimens such as tissue, blood, urine, or saliva from women with and without diagnosed breast cancer. The purpose is to compare these samples between the two groups, which can help in understanding the differences in biological markers.

Participants will undergo procedures to collect these specimens. For those with breast cancer, samples may be taken from both the involved and uninvolved breast if they have not had surgery yet. The study also allows women with Stage 0-III breast cancer to donate tissue and blood, while those with Stage IV can participate in other study aspects.

• Who can participate: Women aged 18 and older, both with and without breast cancer, are eligible. Those with early-stage breast cancer (Stage 0-III) can donate tissue and blood, while those with Stage IV can participate in other study aspects.
• Study details: Participants will donate specimens such as tissue, blood, urine, or saliva. An inactive substance that looks like the investigational medicine/vaccine but does not contain any medicine may be used. Women should not have received chemotherapy or biological therapy within 90 days. Women with breast implants or certain medical conditions may be excluded.
